What are user stories?

User stories are short, simple descriptions of a software feature written from the end user’s point of view.
They focus on the goal and value for the user, not on technical details or implementation.
Each story captures who the user is, what they want to do, and why they need it.

Typical format:

As a [type of user], I want [goal] so that [reason or benefit].

Example:

As a registered user, I want to reset my password so that I can access my account if I forget it.

Why user stories matter

User stories help teams and clients stay aligned around value, not just features.
They promote collaboration, clarity, and incremental delivery.

Benefits include:

Structure of a good user story

A well-written story contains three parts:

  1. Card - the story itself, short and descriptive
  2. Conversation - ongoing discussion between team and stakeholders
  3. Confirmation - clear acceptance criteria defining when it’s done

This approach ensures both clarity and validation.

How to write effective user stories

1. Keep them user focused

Describe what the user needs, not how to build it.
Bad: “Add a new password reset API.”
Good: “As a user, I want to reset my password by email.”

2. Keep them small

Each story should be small enough to complete in one sprint or iteration.
If too big, break it down into smaller, testable stories.

3. Make them testable

Every story must have measurable acceptance criteria that define done.

4. Use clear language

Avoid vague words like “simple”, “easy”, or “modern”.
Be specific about actions and outcomes.

5. Include value

Always capture the “so that” part. It explains why the feature matters.

Example user stories

Authentication

Shopping cart

Dashboard

INVEST criteria for user stories

Good user stories follow the INVEST model:

LetterMeaningDescription
IIndependentStory can be developed and delivered separately
NNegotiableDetails can be discussed and refined
VValuableDelivers value to the user or business
EEstimableTeam can estimate time or effort
SSmallCan be completed within a single iteration
TTestableAcceptance criteria confirm completion

Connecting user stories to acceptance criteria

Every story should include or reference clear acceptance criteria.
They define exactly what must happen for the story to be considered done.

Example:

Story: As a user, I want to log in with my email and password.
Acceptance criteria:

  • User enters valid credentials and sees dashboard.
  • Invalid credentials show error message.
  • Login takes less than 2 seconds.

User stories vs tasks vs epics

LevelDescriptionExample
EpicLarge feature or theme made up of multiple storiesUser authentication
User storySmall unit of value for the userPassword reset by email
TaskTechnical action required to complete a storyConfigure SMTP integration

Common mistakes

  1. Too technical - focuses on implementation, not user value
  2. Too big - describes an entire feature, not a single action
  3. Missing acceptance criteria - unclear when it’s done
  4. No value statement - missing the “so that” part
  5. Ambiguous language - multiple interpretations possible

Best practices
